Hi Austin Hebert,
I think I was able to make a match for your Tableau Public version using dual axis maps and the Lat and Long measures instead of the Latitude(generated) and Longitude(generated) values...which I think you are using in the Public workbook and that you are using to map your short zipcodes in Sheet 1 of the twbx that you attached.
If you use the Lat and Long dimensions instead you should get the actual location instead of the zip code centroid. I don't know the data well enough to identify if this looks right or not in terms of locations...
Here is the side-by-side comparison of the two methods with edits to your workbook attached...:
Volume by Zip2-seb.twbx 312.4 KB
Thank you very much I tried that solution however I changed the zip codes from an average to a dimension. Could you explain to me why the average zip code works instead of setting it to a dimension.
I assume that you're asking about the lat and lon fields being dimensions? I'm not sure why it didn't work for you with changing from an average to a dimension. It works for me so long as I have both axes as continuous dimensions - see below:
If you have a workbook with the 'broken' version with the dimension I'll take a look if you upload it.
In the image you just posted you can see that the volumes in the zip code areas no longer mirror the zip codes in the original file you uploaded.
Ah, okay...what I think is happening is that when you use lat and lon as dimensions it isn't aggregating all of the data across the zip code polygon, so you're just seeing ONE of the records for that polygon displayed. With the Lat and Lon as dimensions, it seems that all of the data is there, but it's stacked and not counted (a selection of one of the polygons on the map shows me that there are many polygon marks being drawn, but I only see the value assigned to the one drawn on TOP).
So, yes, my image didn't have the same base data showing (since I'm not familiar with the data I didn't catch that change in aggregation at all).
Is there a reason you need to have the Lat and Lon as dimensions instead of measures?
No there is not reason, I just thought that was more correct. I'm fairly new to Tableau.
